Simplify the following expression log(25x^3) +3log(1/x)

= ㏒25

Step-by-step explanation:

log25x³ + 3log1/x

According to one of of the laws of logarithm which states : b log a = log a^b

So, 3 log 1/x = log (1/x)³

Another law states that : log a + log b = log a * b

So, log 25x³ +  log (1/x)³ = log (25x³) * (1/x)³

log (25x³)/x³

= log 25

The simplified form is
